I don't think the ref is soft throughout the match, just a bit inconsistent. Tavernier was getting beat up every now and then and United players escape bookings. Then Mbeumo fall down and a booking was called. Good thing the cherries are playing in Vitality so even when they're losing momentum, they pick up pretty quickly again. Then Jimenez had to concede an unnecessary penalty after a great first half display. Notably, both Petrovic and Lammens's saves were immense. A result that both of them deserve for the way they performed.
